持续负载应用
Continuous Load Application
这种应用主要用于那些需求一定转速但是对转速精度请求不高的范畴,比方风扇、抽水机、吹习尚等一类的应用。通常这类应用本钱比拟低且多是开环控制。
This kind of application is mainly used in those areas that require a certain speed but require a low speed accuracy, such as fans, pumps, blowers and so on. Usually, this kind of application costs less than others and is mostly open-loop control.
可变负载应用
Variable Load Applications
这类主要指的是电机转速需求在某个范围内变化的应用,在这类应用中主要对电机的高转速特性和动态响应特性有更高的请求。家用用具中的洗衣机、甩干机和紧缩机就是很好的例子。在汽车工业范畴,油泵控制、电控制器、发起机控制和电子工具等也是很好的例子。在航空范畴也有很多的应用,比方离心机、泵、机械臂、陀螺仪等等。这个范畴中多运用电机反应器件组成半开环和闭环停止控制。这就需求复杂的控制算法,增加了控制器的复杂水平也增加了系统本钱。

This kind of application mainly refers to the application in which the motor speed requirement varies in a certain range. In this kind of application, there are higher requests for the high speed characteristics and dynamic response characteristics of the motor. Washing machines, dryers and tighteners in household appliances are good examples. In the automotive industry, fuel pump control, electrical controller, engine control and electronic tools are also good examples. There are also many applications in aviation, such as centrifuges, pumps, manipulators, gyroscopes and so on. In this category, motor reactor components are often used to form semi-open-loop and closed-loop stop control. This requires a complex control algorithm, which increases the complexity of the controller and the cost of the system.
定位应用
Location application
大多数的工业控制和自动控制方面的应用属于这个类别。在这些应用中常常会完成能量的保送,如齿轮或者传送带,因而系统对电机的转速的动态响应和转矩有特别的请求,同时这些应用也可能需求随时的改动电机的转向,电机可能工作在匀速,加速,减少阶段,而且有可能在这些阶段中负载也在变化,所以这对控制器提出了更高的请求,通常这种控制运用闭环控制,以至会有扭矩环、速度环和位置环三个控制环。测速时可能会用上光电编码器和一些同步设备。有时分这些传感器会被用于丈量相对位置,也有时分用于丈量绝对位置。过程控制、机械控制和运输控制很多都属于这类应用。
Most industrial control and automatic control applications fall into this category. In these applications, energy delivery is often completed, such as gears or conveyor belts, so the system has special requests for the dynamic response and torque of the motor speed. At the same time, these applications may need to change the direction of the motor at any time. The motor may work at a constant speed, acceleration, reduction stage, and possibly in these stages. Load is also changing in the stage, so it makes higher request to the controller. Usually this control uses closed-loop control, so that there are three control loops: torque loop, speed loop and position loop. Photoelectric encoders and some synchronization devices may be used in speed measurement. Sometimes these sensors are used to measure relative position, and sometimes absolute position. Process control, mechanical control and transportation control are many of these applications.
